To all whom it may concern Be it known that I, HIRAM S. UTLEY, a citizen oi' the United States, residing in the city of Chicago, in the county of Cook and State scription.

the following is a full, clear, and exact de- This invention relates compounds used for making artificial stone, tiles, plaster for walls v and pillars, statuary and ornamental molding of glue dissolved in five of any kind, and has for its object to provide a new and useful composition of matter for the above purposes, which shall possess in the .mesi use. as!

In carrying out my invention, I employ the following ingredients, in substantially the proportions enumerated, to wit: one pound gallons of water. Next take thirty parts of the resultant glue water and mix with one part ofsaturated s0- lution of sugar of lead or bichromate oi potash. Then, with the solution th us formed, mix

a suiiicientamount of plasterof paris to make of the whole a plastic body. The compost tion thus made can he used. for a variety of purposes, such as for artificial stone, for tiles, or plaster, or for ornamental molding of any kind. A very high grade of imitation marble may be made of the same compound by 1nix-' ing suitable coloring matter with the compound while in a plastic state, in any well known manner,ortwo or more batches of the compound of different colors niay be intermixed so'as to produce an artificial marble having characteristics closely resembling the natural stone.

The gl'uewater serves to sutticiently retard the setting of the compound so that it is adapted for the various uses referred to, as well as other uses which will readily sugtrest themselves to one skilled in the art, While the sugar of lead or biehromatc of potash serves to render the compound almost as hard as natural stone.

It is preferable to use sugar of lead instead of bichromate of potash when Tile, Plaster, &0., of which to improvements in' the/com pletell article is to be decorated with light colors, because ofits transparency.

The compound has several highly desirable qualities aside from its hardness and tough.

will penetrate or sink into the stone in propo'rt'ion to the amount of color applied, thus preserving" the same outline and design, so that the surface of the compound can be repeatedly cut away or worn off without materially afiecting or altering the design originally applied to the surface.

The various articles made from this'compound are all made by a cold process, not re quirinn the use of heat of any kind at any time, for the composition sets naturally in about ten hours and sets very hard, after which it may be ornamented or polished, or

both, in any well known or desired manner.

Articles made of this compound'may be used in either interior or exterior decoration or finish, as the compound, when set, is praotically as impervious to moisture as natural stone, the combined effect of. the glue and bichromate ot potash or sugar of lead produc ing this desirable result, so thatthe materia when exposed to the elements or original shape.
